Hi, suddenly i cannot connect to my mybook.
I can see the files \\bullfrog… but i cannot in any way connect by saying http://… I just get the "Internet Explorer cannot display the webpage".
Any ideas..??

I am having the exact same issue all of a sudden. Yesterday, I was able to http to http://MyBookIP:8080 as well as https://MyBookIp:3210 and get to the pages, but it suddenly stopped working. I can still access the shares as well as ssh into the machine, but for some reason, none of the http or https addresses connect, I just get the "Internet Explorer Cannot Display the Webpage" as you said….can anyone tell me how to fix this through SSH since I can still access the system?

when i run lighttpd.sh stop then lighttpd.sh start, it still does not allow web access. I do get the following errors though:

[root@MyBookWorld init.d]# ./lighttpd.sh start
Starting lighttpd
[root@MyBookWorld init.d]# 2010-09-15 09:02:21: (mod_fastcgi.c.892) execve faile d for: /opt/bin/php-fcgi No such file or directory
2010-09-15 09:02:21: (mod_fastcgi.c.920) child exited: 2
2010-09-15 09:02:21: (mod_fastcgi.c.923) if you try do run PHP as FastCGI backen d make sure you use the FastCGI enabled version.
You can find out if it is the right one by executing 'php -v' and it should disp lay '(cgi-fcgi)' in the output, NOT (cgi) NOR (cli)
For more information check http://www.lighttpd.net/documentation/fastcgi.html#pr eparing-php-as-a-fastcgi-program
2010-09-15 09:02:21: (mod_fastcgi.c.1200) [ERROR]: spawning fcgi failed.
2010-09-15 09:02:21: (server.c.673) Configuration of plugins failed. Going down.

Upon seeing this, I installed ipkg php-fcgi. Once I did this and ran the lighttpd.sh start again, I have access to the web interface! Wow, I don't quite know what happened, but somehow the php-fcgi must have become uninstalled, so thank you so much!

I seem to have the same issue. I do have transmission up and running and can connect to the web interface for it at http://mybookworld:9091, but http://mybookworld acts as if there is no server at that address. As others have described, all other services are running as normal - nfs, ftp, ssh are all accessible. Only the web interface is down. I followed the "tutorial"…..
DUH!
I followed the tutorial for webdav. In that tutorial, you are instructed to add the line mod_webdav to the file /etc/lighttpd/lighttpd.conf. Upon removing this line and restarting the lighttpd server, the web interface began to work.
I hope this will help some of you.
